On February 13, 2017, two eighth-grade friends, Abigail “Abby” Williams and Liberty “Libby” German, were dropped off to walk the Monon High Bridge Trail in the small town of Delphi, Indiana. They never came home. The next day they were found dead in the woods nearby. The only solid lead was a few seconds of video Libby had quietly recorded on her phone — a man on the bridge, and a voice saying “down the hill.” For five years, the entire country searched for “Bridge Guy.” In 2022, police finally arrested a local pharmacy worker named Richard Allen.

A Walk on the Bridge

It was a mild day off school, and the two girls — 13-year-old Abby and 14-year-old Libby — asked to be dropped at the trails near the old Monon High Bridge, a rusted railroad trestle that stretches high over Deer Creek on the edge of town. When a family member returned to pick them up that afternoon, the girls were gone and not answering their phones. A search began that evening, and the next day their bodies were found in the woods across the creek from the bridge.

The Evidence Libby Saved

In the last minutes of her life, Libby German did something that would shape the entire investigation: she turned on her phone. The device captured grainy footage of a man walking on the bridge, along with a short piece of audio in which a voice tells the girls “down the hill.” Investigators released the image and the audio to the public, and “Bridge Guy” became one of the most-viewed pieces of evidence in modern American crime.

Police later released composite sketches of a suspect and an enhanced video, asking anyone who recognized the figure or the voice to come forward. Tips poured in by the tens of thousands. For a while, it seemed the answer had to be just one phone call away.

Five Years of Dead Ends

It was not. Years passed with no arrest. Investigators released a second, very different suspect sketch in 2019, fueling speculation that they had lost the trail entirely. Delphi, a town of a few thousand people, lived under the weight of an unsolved double murder and the unsettling possibility that the killer was someone local — someone who had perhaps stood in the same checkout lines and attended the same vigils as the grieving families.

The Arrest

In October 2022, more than five years after the murders, police arrested Richard Allen, a worker at a local pharmacy who had lived in Delphi the entire time. A key piece of physical evidence was an unspent .40-caliber bullet found between the girls’ bodies, which a firearms examiner linked to a handgun owned by Allen. He had, it turned out, even come forward years earlier to say he had been at the trails that day — a report that had slipped through the cracks.

The Trial

Allen’s trial began in October 2024. Prosecutors told jurors that he had confessed to the killings dozens of times while in custody — to his wife, his mother, prison staff, and other inmates — and pointed to the bullet linked to his gun. His defense team argued that the confessions were the unreliable product of a man deteriorating in harsh solitary confinement, and maintained his innocence.

On November 11, 2024, the jury found Richard Allen guilty on all counts. On December 20, 2024, he was sentenced to 130 years in prison. His defense has continued to maintain his innocence and has pursued an appeal.

Why This Case Still Matters

The Delphi case became a national obsession for many reasons — the small-town setting, the long years without answers, the haunting clip of a stranger on a bridge. But at its center is a single, almost unbearable fact: a fourteen-year-old girl, sensing danger, had the presence of mind to start recording, and what she captured would one day stand in a courtroom.

The case also shows both the power and the strain of the internet-age investigation. Millions of people studied that video; armchair detectives named and harassed innocent men along the way. The tips helped, and they also hurt. In the end it was old-fashioned police work and a piece of ballistic evidence — not a viral theory — that brought a conviction.

Libby German was fourteen years old, and in the last minutes of her life she turned on her camera. It took more than seven years, but that recording helped put a man in prison for the rest of his life. So what does it say about us that two kids on a country bridge became the case a whole nation couldn’t look away from — and would we still be talking about it if Libby hadn’t pressed record?
